السلام عليكم
hello everyone
this is my first project at instructable ,..
i am sorry because I'not really good in English but i can give you the main idea.
today i will help you to know some information about Breadboard actually bad breadboard and how to improve it to be easy to use.
there are breadboards haven't markes (blue & red) and have two part" every part 30 strips "
anyway every body have this problem in his breadboards, have to complete reading this instructable.

Step 1: First of All :

a /Breadboard/or/Testboard/or/protoboard/ is a construction base for prototyping of electronics.
we use breadboard because the solderless breadboard for electronics does not require soldering, it's reusable, & this is makes it easy to use for creating temporary prototypes and experimenting with circuit design

Step 2: Basics

in testboard the hole patern for a typical etched prototyping PCB is similar to the node patern of the solderless Testboards.. shown above
- the layout of a typical breadboard is made up from tow types of areas called strips, strips consist of inter connected electrical terminals

Step 3: Terminal Strips

the main areas to hold most of the electronics components we can find horizontal row holes unconnected marked as A,B,C,D,E and F,G,H,I,J

Step 4: Bus Strips

to provide power to the electronic components a bus strip usually contain tow columns one for ground and one for supply voltage

Step 5: The Main Idea

if you ready.. bring your pens ,red and blue and a ruler . and start working like a pictures

Step 6: Connect Just Ground Together

if you need you can connect the group of ground with 30 strips with other group of ground by a small wire ..
finally the breadboard it well be good and easy to use
,
in the end thanks for reading and i'am so sorry because my English is horrible.
pray for peace in my country 'syria' :'(
thank you :-)
